As shown in Figure 3b, the differentially expressed proteins in the comparison of PC versus CC were enriched in vasopressin-regulated water reabsorption, IL-17 signaling pathway, African trypanosomiasis, pyrimidine metabolism, cholesterol metabolism, thyroid-hormone synthesis, and peroxisome proliferator-activated receptor (PPAR) signaling pathway (p < 0.05). The gene discussed is IL17A; the disease is human African trypanosomiasis.
